Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed August 21, 1907. Serial No. 389,463.

T 0 all whom it may concern:

Be it known that 1, JOHN FRED. BADGER, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented a new anduseful Improvement in Tire-Upsetter, Punch, and Shear Machines, of whichthe following is a specification.

The object of my invention is to provide a powerful and efficient tireupsetter for upsetting or shrinking tires on the Wheels of vehicles,either hot or cold, and which also shall be capable of performing thework of shearing, punching, &c.

My invention consists in the novel construction and arrangement of theparts which I will now proceed to describe with reference to thedrawings, in which Figure 1 is a front elevation of the entire machine.Fig. 2 is a vertical transverse section on line 22 of Fig. 1. Fig. 3 isan enlarged sectional view on line 33 of Fig. 1, showing the grippingjaws and the tire of the wheel engaged thereby. Fig. 4 is a section online 44 of Fig. 3. Fig. 5 is a detail in perspective of the lower end ofone of the main gripping levers, Figs. 6, 7 and 8 are details ofmodifications.

- In the drawing, X represents the main frame consisting of two uprightparallel and similarly shaped castingsor plates connected together. Atabout the center of each plate is fulcrumed at a a pair of grippinglevers A A hearing gripping devices designed to seize and upset the tireof a wheel WV when placed between the two plates of the main frame.There are four of these gripping levers, two on one side of the wheel,and two on the opposite side, the gripping devices of the levers on oneside of the wheel cooperating with the gripping devices on the oppositeside of the wheel to pinch and grip the tire between them preparatory toa movement toward each other to upset or shrink the tire.

The gripping levers extend upwardly to the top of the frame in divergentrelation and at their up er ends are connected to the plungers ofhydraulic jacks or ram cylinders B, so that when water oil or steam isforced into these cylinders the levers A A are brought together with apowerful action.

. Each lever A, see Figs. 2, 3, 4, has on its inner side a transverseguideway K in which are arranged sliding gripping jaws J which .in Fig.2.

have teeth on their inner edges adapted to grip the edge of the tire.These gripping jaws are of T-shape in cross section, as seen in Fig. 3,and have along their upper edges rack teeth a adapted to be engaged bythe inions m men a transverse shaft 1, journaled in the o posite leversA A and having a turning cran k arm 0, Figs. 1 and 2, for adjusting thegripping jaws in their guides. The gripping jaws are of wedge shape, asseen in Fig. 4, so that the inward strain of the levers'A and guidesockets in upsetting the tire, will wedge against the gripping jaws andjam the gripping jaws against the tire. To loosen and adjust the jaws,in applying them to, or removing their gripping contact with the tire,the shaft Z and pinions m are rotated by the crank handle 0.

The upper ends of the main frame plates are arched, as seen in Fig. 1,and at a point midway between the levers A A is supported an adjustablestop foot C whose lower edge is curved to correspond to the curve of thewheel and whose upper end is provided with rack teeth engaged by apinion c ona transverse shaft'c, provided with a crank arm for turningit. By turning this crank arm and shaft, the'stop foot 0 may be adjusteddown to solid contact with the tire, as seen in Fig. 2, or be elevatedto a distance above the same, as seen in Fig. 1. The foot is to berigidly held in either of these positions by means of a locking pin t. i

To lift the wheel up to the gripping jaws, and also hold it against thefoot C when the latter is down as in Fig. 2 a transverse lever D with acurved saddle d is provided as seen This lever is projected through thewheel until a pin in its end is received into an open fulcrum seat 61and the lever is then raised to cause the saddle d to lift the felly ofthe wheel to position and when in said position the position of thelever is fixed by a detent d which is pivoted to the lever and is madeto engage one of a series of ratchet teeth (1 on the frame plate. I 7

My machine is designed to upset tires either cold or hot. Small tiresmay be upset cold, but whenthe tire is above a certain cross section itis necessary to soften the iron by heating. torch E is mounted upon abracket inside themainframe and has its flame spout, or burner For thispurpose a gasolene whereby the same machine may be made to 6, broughtdown close to the tire at a point I between the gripping jaws. When theflame v of this torch is applied to the tire, theflfoofnC- is firstelevated, as seen in'Fig.'1-, and assoon as the texture of the ironhasbeensufiiciently softened by heat the foot 0 is brought down solidlythereon and power applied to bIlIl the two sets of leversand grippingjawsto gether to upset the tire, the buckling of the tire beingprevented by the curved abutting face of the foot. The levers A A can bebrought together at the same time or can operate separately according tothe requirements of the wheel. 7

In conjunction with the upsetting function of my machine, I also providemeans perform various operations in metal working, such as shearinriveting, punching &c. For this purpose the lower ends of one pair oflevers A are extended beyond their fulcrums, as seen in- Fig. 5, andprovided with a stout laterally projecting pin A. This pin 'playsthrough a slot in the frame plate and enters an elongated hole in ashear jaw S, Fig. 1, which cooperates with a stationary shear plate 8arranged below the movable jaw C, so that when the machine is not in usefor upsetting tires, the same organization of devices permits themovement-of the levers to be utilized for shearing. In like manner, alever P on the other side is provided with graduated punches adapted tocooperate with a perforated die plate 19 attached to the frame plate,and there may be two of these supplementary attachments on each of themain frame plates cooperating with'the two' main levers of each plate. 7r

In making use of my invention where great power is required, I mayinterpose between the main levers and the hydraulic plunger a set of comounding levers as seen 1n Fig. 6, in which A A are the compoundinglevers connecting the jack plungers to' the said levers, the saidcompounding levers being jointed to each other at the top to give atoggle effect.

If it is not desired to use a hydraulic pump or jack, but a purelymechanical means of operation, I may employ the construction shown inFig. 7 in which the levers A and A are brought together by a right andleft screw extending through trunnion nuts in the lower slotted ends oflevers A. On this double screw shaft is fixed a gear wheel G engaged'bya pinion H on a shaft I, turned by a band wheel or crank J. Where butlittle power is required, the simple construction shown in Fig. 8 may beemployed. In this case an arc-shaped tooth bar A is formed on the upperends of each of the gripping levers A whlch toothed bars are directlyengaged by pinions A on a shaft turned by the crank A.

In my machine it will be seen that the upnofnthe plate,

setting is done at the top of the wheel in position for easy inspectionby the workman each side plate X h'as an arch bar at the top connectedby upright standards to the body it will be seen that the point atwhich'the upsetting operation is performed is entirelyopen forinspection and the manipulation of the torch and presser foot as wellas-of the gripping jaws, and the frame affords at the top a convenientmeans for supporting 3 and holding the hydraulic cylinders or other Thema'c'hineis als o a very power appliance.

economical one for the wheelwright, since it embodies the functions ofseveral machines in one'and' taking up but little floor space.

In carrying out my invention itjwill be understood that many changes inthe details of construction may be made without depart- .ing' frommyfinvention as set forth in the claims. V r i I claim 1.
